High-Reliability Condition Monitoring for Industrial Rotating Assets
The Bently Nevada 330102-00-79-05-02-05 3300 XL 8 mm Proximity Probe is a non-contact eddy-current sensor designed for precise measurement of shaft vibration, radial displacement, and position in rotating machinery. As part of the trusted 3300 XL proximity transducer system, it delivers stable signal output, strong noise immunity, and long-term measurement reliability in demanding industrial environments.
This configuration (…00-79-05-02-05) is typically associated with a standard 8 mm probe body design, ~7.9-inch class mechanical length variant, 1.0-meter system cable, ClickLoc connector, and CSA/ATEX/IECEx certified option (05). According to 3300 XL ordering structure references, the “79” family is among the longer probe configurations used in deep mounting applications where extended reach into bearing housings or machine casings is required.
Built with stainless steel housing and a PPS sensing tip, it is engineered for continuous operation in harsh environments involving vibration, thermal cycling, and industrial contamination.
